This part is recalling the tales of Hades. Yet that it is an older tale as well.
What i find most curious about all reports about the afterlife is that they are culturally informed and colored by the underlying beliefs of the society originating the spirits. That is extremely important simply because if you do not believe in such an after life you will pass to an afterlife containing those who think as yourself. Other reports suggests that this can even be unpleasant particularly if it involves rejection of compassion or the mere existence of the spirit life.
Yet the spirit will be aware of been aware however grey and lost he feels. Thus we get real lost spirits or ghosts who take far longer to move forward.
Before the advent of Jesus and we had no indication of the existence of the idea of grace in either religion or in our tales of the afterlife. With Grace the after life becomes a place of preparation for more improvement through helping others. Has his teaching been sufficient to actually change out the other side itself?..
